The light is made my L3 insight (EOTech) its their new-ish line of AA battery operated weapons lights. 150 lumen with full on, momentary on, and strobe mode.
SUPER THIN light, and has "paddles"in the back of the light to actuate it, so, when your left hand in on the lower handguard, your finger can manipulate the light without moving your grip. Also, it attaches to the rail with a quick throw lever, which is nice too..
Im very pleased with it.. I know what your thinking after looking at my Tavor... I should get EOTech to sponsor me! lol
